one-eyed_jim Old School Grand Master Mar 8, 2008 #11 No problem. I've been running SRAM PC59 chains on a 7-speed STX bike for years. Shifting's fine.
A Anthony Retrobike Rider Mar 8, 2008 #12 You can't use a 7/8-speed chain on a 9-speed set up because it's too wide for the gaps in the cassette so it's liable to foul the next biggest sprocket. But there's nothing to stop you using a 9-speed chain on a 7/8-speed set up.
